(2017-12)Neospora caninum, an intracellular protozoan parasite from the phylum Apicomplexa, is the etiologic agent of neosporosis, a disease considered as a major cause of reproductive loss in cattle and neuromuscular disease in ... -
Application of network analysis and cluster analysis for better prevention and control of swine diseases in Argentina
(Plos One, 2020-06)Rationale/background: Though much smaller than the bovine industry, the porcine sector in Argentina involves a large number of farms and represents a significant economic sector. In recent years Argentina has implemented ... -
Assessment of Influential Factors for Scours Associated with Cryptosporidium sp., Rotavirus and Coronavirus in Calves from Argentinean Dairy Farms
(MDPI, 2021-09)Scours is the most common disease in dairy calves, and it is a multifactorial syndrome complex. Cryptosporidium sp. (C. sp.), rotavirus group A (RVA), and bovine coronavirus (BCoV) are the three main pathogens associated ... -
Assessment of the potential utility of different regions of Streptococcus uberis adhesion molecule (SUAM) for mastitis subunit vaccine development
(2017-04)Streptococcus uberis is one of the most prevalent pathogens causing clinical and subclinical mastitis worldwide. Among bacterial factors involved in intramammary infections caused by this organism, S. uberis adhesion ... -
Association between spoligotype-VNTR types and virulence of Mycobacterium bovis in cattle
(Taylor & Francis, 2014-01)Mycobacterium bovis is the causative agent of bovine tuberculosis, a disease that affects approximately 5% of Argentine cattle. The aim of this research was to study if it is possible to infer the degree of virulence of ... -
Ataxia enzoótica tardía en corderos asociada a deficiencia de cobre en una majada de la región semiárida central Argentina = Late enzootic ataxia in lambs associated with copper deficiency in a herd of the semi-arid central region of Argentina
(Facultad de Agronomía y Veterinaria, Universidad Nacional de Río Cuarto, 2022-12)El cobre (Cu) participa entre otras funciones del proceso de mielinización del sistema nervioso central del feto. Ante una deficiencia durante la gestación, los corderos nacidos pueden desarrollar un cuadro con signos ... -
Babesia bovis biological clones and the inter-strain allelic diversity of the Bv80 gene support subpopulation selection as a mechanism involved in the attenuation of two virulent isolates
(Elsevier, 2012-12-21)The virulence phenotype of Babesia bovis subpopulations was evaluated using biological clones derived from the high-virulence BboS2P and the low-virulence BboR1A strain and two original virulent isolates, BboL15 and BboL17, ... -
Babesia spp. in ticks and wildlife in different habitat types of Slovakia
(2016)Background: Babesiosis is an emerging and potentially zoonotic disease caused by tick-borne piroplasmids of the Babesia genus. New genetic variants of piroplasmids with unknown associations to vectors and hosts are ... -
